T all whom it may concern: A removable cap-plate or cover, E, having Be it known that I, ll/IANOEL \V. MITCHELL, flanges or ribs e fitting tightly within the two of New Albany, in the county of Floyd and side walls and end wall of the protector,shields State of Indiana, have invented a new and Imthe top of the beam end I) from the superposed 55 proved Beam-End Protector, of which the folbrick or stone or other material of the wall 0, lowing is a full, clear, and exact description. into which the protectors and beams are built, My invention relates to protectors for the as above described. I make a recess, d,in the ends of beams or timbers set into walls of bottom wall or fioor of the protector-casing A, buildings or elsewhere, and has for its object to give free air-circulation below the beam 60 to provide a simple, inexpensive, and efficient without interfering with its firm support on device of this character which will promote the floor of the casing,said recess d being practhe durability of the beams and their supporttically a part of the airspace D, which suring-walls. rounds the end of the beam,all as will readily The invention consists in certain novel feabe understood from Figs. 1, 2, and 3 of the 65 r 5 tures of construction of the beam-end protector, drawings.
